[Potential biases in epidemiological studies using respondent-driven sampling method: a comparison between its face-to-face and online application.].

In epidemiological and social studies on populations without a sampling frame or that are hard to reach, respondent-driven sampling (RDS), under certain assumptions, has the potential to produce asymptotically unbiased and efficient population estimates for these populations. While RDS is typically conducted face-to-face, the online version (WebRDS) has gained attention due to its potential advantages, although its disadvantages have also raised concern. The objective of this study was to contrast these two formats at the level of application and potential biases, where the online version offers improved speed and lower costs but raises concerns about potential biases due to a lack of face-to-face instructions regarding definition of the social network size and peer-recruiting process.

Women working as cleaners in Spain: working conditions and use of psychotropic drugs.

Goals: To describe the exposure to psychosocial risks at work and the consumption of psychotropic drugs and opioids among women working as cleaners; and to analyse the association between their exposure to psychosocial risks and drug use.

Methods: Observational cross-sectional study based on an online survey (collected during April and May 2021) from the wage-earning population in Spain. In this study, only women working in manual occupations were included (n=3430).

Job Insecurity, Mental Health, and General Health Over Time: A Longitudinal Update of a Cross-sectional Study.

Objective: The aim of the study is to test the relationship between different conceptualizations of job insecurity and health over time by applying a longitudinal design.

Methods: 543 workers were reinterviewed after 1 year to check if being exposed to job insecurity affected their general and mental health. Robust Poisson regressions were fitted to calculate the incidence rate ratio between job insecurities and two health outcomes.

Protective action in the workplace in the time of COVID-19: The role of worker representation.

Background: This study addresses the contribution of worker representation to health and safety in the pandemic context. To do so, we examine whether the self-reported presence of representatives in workplaces is associated with the implementation of anti-COVID-19 protective action and with which type of measures their existence is most strongly associated (individual, collective or organizational). The article also explores how the presence of worker representatives and anti-COVID-19 protective measures are distributed according to workers' socio-professional characteristics and company features.

Sickness Presenteeism and Psychosocial Risk Factors According to Inequality Axes.

To assess the association between psychosocial risk factors (PSRs) and sickness presenteeism (SP) and examine possible differences according to the major axes of inequality in the labor market. Methods: Cross-sectional study based on a representative sample of the Spanish salaried population. Results: Although nearly all PSR show crude associations with SP, when adjusted for every other PSR, only the workers exposed to lack of role clarity (adjusted prevalence ratio [aPR], 1.

Is clinical coordination across care levels different according to the secondary care medical speciality? Results from the Catalan health system.

Background: Despite the scarce evidence, some studies suggest that cross-level clinical coordination may vary among secondary care (SC) doctors, influenced by their speciality and organisational model, including degree of decentralisation to primary care (PC). The aim was to determine the differences in experience and perception of cross-level clinical coordination and related factors according to the SC doctor's speciality in the Catalan health system.

Methods: Cross-sectional study, based on an on-line survey using the COORDENA-CAT questionnaire, to SC doctors (n = 1666).

Mental health inequalities in times of crisis: evolution between 2005 and 2021 among the Spanish salaried population.

Background: Studying the working population's mental health in times of crisis (such as the 2008 recession or the COVID-19 pandemic) is very relevant. This study aims to assess the prevalence of poor mental health among the Spanish salaried population, according to the labour market inequality axes (2005-2021).

Methods: Repeated cross-sectional study by comparing different surveys from 2005, 2010, 2016 and 2021 on workers residing in Spain who had been working in a salaried job during the week preceding the survey.

[Does the integration of health services management improve clinical coordination? Experience in Catalonia].

Objective: To analyze the experience and perception of clinical coordination across care levels and doctor's organizational and interactional related factors, according to the type of management integration of the healthcare services of the area, in Catalonia.

Method: Cross-sectional study based on an online survey by self-administration of the questionnaire COORDENA-CAT.

Data Collection: October-December 2017.

Understanding How to Improve the Use of Clinical Coordination Mechanisms between Primary and Secondary Care Doctors: Clues from Catalonia.

Clinical coordination between primary (PC) and secondary care (SC) is a challenge for health systems, and clinical coordination mechanisms (CCM) play an important role in the interface between care levels. It is therefore essential to understand the elements that may hinder their use. This study aims to analyze the level of use of CCM, the difficulties and factors associated with their use, and suggestions for improving clinical coordination.

Do primary and secondary care doctors have a different experience and perception of cross-level clinical coordination? Results of a cross-sectional study in the Catalan National Health System (Spain).

Background: Clinical coordination across care levels is a priority for health systems around the world, especially for those based on primary health care. The aim of this study is to analyse the degree of clinical information and clinical management coordination across healthcare levels in the Catalan national health system experienced by primary (PC) and secondary care (SC) doctors and explore the associated factors.

Methods: Cross-sectional study based on an online survey using the self-administered questionnaire COORDENA-CAT.
